E-to-X-band phase detector for analog carrier recovery techniques

摘要

A compact inductorless phase detector MMIC of E-band and X-band signals is presented. The phase detector is combined with frequency divider-by-8 and CMOS DC output buffer to provide high detector gain. The phase detector sports the detector gain of 0.2 V/rad with very high sensitivity of -42 dBm at the frequency of 75.2 GHz. The circuit realized in an SiGe BiCMOS 0.13μm process draws 75 mA with the supply voltage of 4V and is intended to serve as an element of a millimeter-wave carrier recovery system.
